En serio: el acuerdo de licencia para las claves de Techet no permite que se entreguen a nadie. Ni siquiera a los miembros de la familia de forma gratuita.

eBay todavía tiene muchas ofertas de claves altamente sospechosas a muy bajo costo.

It's a very strange business, but lucrative after all...

Unless it was a big supplier (HP, Dell, Toshiba etc.), I'd say chances are that your key comes originally from a dodgy Chinese site such as this one: http://www.softwaresoem.com/supplier-105881-windows-7-product-key-sticker

Here in Europe, the market is still flooded with this crap.

I wouldn't take the chance of re-using it. It might not be possible.

As long as the system remains activated, don't worry about it. I think MS no longer deactivates Win 7 systems when they block the matching key some time later after activation. At least, I've not heard about any such cases for years.

Ok, thank you very much for your time.

By the way, here in Latin America that happens a lot too, due to the high piracy. I know that many can not cost the products legally, but in the long run it is very annoying when it comes to backing up data or preventing future accidents.
In short, a greeting.

I've seen this message before. It tends to turn up when the key is counterfeit. Where did you get your key from?

It is the code that comes on the sticker of a pre-assembled team. I thought it would be just as valid as one bought online.
Also, my operating system is registered, since I can receive updates.
Is it because you're already registered, which invalidates re-using it?

I have verified my product key in the Microsoft link, but it fails error. It no longer supports keys for Windows 7? And an apology for my English, it's not very good.
